The end of the world: Start with a gun and build a tank in ten days

"Bang bang bang!"

A series of explosions sounded instantly.

Everyone was stunned by this sudden scene.

Ozawa and the woman subconsciously looked at Lin Nan, while he looked at Chu Mengyao aside with a shocked expression.

Only then did they realize that this thunderous technique was actually the work of the sixteen or seventeen-year-old girl next to them.

I couldn't help but take a breath!

"Well done, Yaoyao, I got three more green crystals!"

Lin Nan patted Chu Mengyao's head and gave one of them to her.

The woman took a very serious look at the dead boy, and then suddenly said,

"I won't go on with you anymore. All my men are dead, and I have to leave here too!"

She looked at Lin Nan, but Lin Nan had no intention of talking to her. He was still looking at the map in his hand carefully.

Ozawa and Chu Mengyao were very concerned about her, so be careful when they go back.

She nodded, stared deeply at Lin Nan's back again, and then completely disappeared into the darkness.

At night in the secret realm, the breeze is cold and cold.

Only the little light at the entrance to the secret realm can give people walking at night some comfort.

After a while, Lin Nan slowly raised his head and walked back and forth around the huge stone pillar for a while.

He was looking for the entrance marked on the map.

But it was not found!

At this moment, Chu Mengyao seemed to have discovered the problem, and she said softly,

"Well, Brother Nan, did you hold the map upside down?!"

"Reverse?"

Lin Nan was stunned for a moment, then flipped the map. He walked around in a large circle and walked behind the stone pillar, and sure enough he saw an entrance!

A faint shimmer of light lingered around, just like the entrance to the secret realm.

"Depend on!

I really got it backwards! "

Lin Nan smiled awkwardly.

"Brother, I'm still curious about why you were able to reach your destination by walking in the opposite direction?!" Chu Mengyao said with a smile again.

When he said this, Lin Nan also became puzzled.

I saw him opening the map again, looking at it for a while and suddenly laughing,

"Good guy, what a mistake. Our original goal was the lair of the second-level elite monster, but we didn't expect to arrive at the entrance to the next level of secret realm!"

Everyone suddenly realized.

"However, it seems that we are not allowed to enter the entrance to this secret realm?"

Ozawa's voice suddenly sounded.

I saw her slowly putting her hand in, and then it was bounced away.

"There is something in my mind telling me that my level is too low to enter!"

Lin Nan didn't believe in evil and put his hand in. At this moment, the system's voice suddenly sounded,

"The host is entering a deeper secret realm. The secret realm level exceeds the host level. Do you want to use the secret realm exploration ticket to enter by force?"

"use!"

Without any hesitation, Lin Nan decided to go in.

A high level also means that there are enough monsters that can explode second-level green crystals, and he is worried that he has no place to look for them!

Why not?

However, after Lin Nan made his decision, the system's voice sounded again,

"It is necessary to remind the host that the strange beasts in the deep secret realm can be chased out from the entrance, so the host please stay vigilant and don't think that there is no danger if you escape from the entrance!"

"Hey, hey, system, please be more confident in me, okay?!

Why should I be chased by them instead of me chasing them? "

"..."

The system didn't speak anymore. Facing Lin Nan's question, it chose silence again.

At this moment, Lin Nan stretched out his arm.

"Let's go, I talked to the person in charge of the secret realm, and he let us in!"

After saying that, he took Chu Mengyao's hand and walked in.

Chu Mengyao naturally didn't believe that Lin Nan had this ability, but Ozawa couldn't help being shocked when he saw that they really walked in without any hindrance.

"Lin Nanjun, I feel more and more like he is omnipotent!"

Then Ozawa also walked in, and the obstructive force disappeared.

The system determined that Ozawa was following them, and let her in.

After they all entered, Lin Nan turned around and counted the people and realized something was wrong.

"Where's that woman?"

The two girls were stunned.

"Which woman?"

"She's the woman whose teammates all died!" Lin Nan said.

"..."

The two of them were speechless.

"They left long ago, don't you know???"

Lin Nan:......

"I'm sorry, but you didn't even say a word to me when you left..."

Lin Nan muttered in his heart, then directly picked up the craniotomy rod and walked away.

The deep secret realm is different from the outside world. There is no sky here, there are just dense caves and forks one after another. In comparison, this place is more like a dungeon in the game.

And the most important thing is that there is no room for aircraft and tanks to play here.

"It is indeed a high-level secret realm. As soon as you enter, you can feel the pressure."

Lin Nan knew that it was danger perception at work!

Looking at these caves, Lin Nan suddenly thought of those giant beetle nests when he first arrived in the secret realm.

The difference is that there is a buzzing sound all around here.

It is quite similar to the sound made by the fireflies before.

Thinking of this, Lin Nan couldn't help but panic.

If a large number of fireflies suddenly appeared, it would be the end of the world!

No matter what he was afraid of, after Lin Nan walked dozens of meters inside, he suddenly caught a glimpse of a bright light coming from a cave.

It was very bright, directly illuminating the stone chamber under his feet!

Accompanied by an even stronger buzzing sound.

Lin Nan felt something was wrong, he walked forward a few meters carefully and looked at the situation in the cave.

It didn't matter if he didn't look, but when he looked, he felt that the grass on his grave had grown to several meters long!

There were thousands of giant fireflies lying on the huge cave rock wall.

If they all came out, it would definitely be a disaster for the three of them!

"Let's go, let's get out of here quickly!"

Lin Nan said in a very small voice, and then stepped back gently.

Although the voice was very small, they didn't even hear it clearly.

But they were not stupid. Seeing Lin Nan's nervous look, they immediately understood that there was a great danger ahead.

When they walked out of the first fork lightly, they suddenly found that a first-level firefly suddenly appeared behind them.

This firefly obviously discovered them.

It was bent all over and kept smacking its lips.

Lin Nan knew that it was preparing to attack!

Once it successfully launches an attack, not to mention whether it will hurt them, the sound alone is likely to attract a large number of fireflies.

Seeing that the burning flames were about to be released, at this critical moment, Chu Mengyao instantly activated the control skill and directly controlled them.

Just when they thought they could breathe a sigh of relief, the second one flew out of the cave.

Control again!

A third one flew out.

Control again!

Until the fourth, the fifth...

Lin Nan was stunned. How come this group came out to the toilet?

In a short while, Chu Mengyao had controlled about 20 first-level giant fireflies.

The reason why she was able to control so many was due to the second-level evolution crystal she had eaten before.

Of course, another important reason is that the fireflies themselves have strong attacks, but their ability to resist mental control is weak!

"How is it, Yaoyao, can you still hold on?"

"Not bad!"

Chu Mengyao nodded.

Facing the fireflies that appeared one after another, the two sides were deadlocked for a while, and finally Lin Nan made a decision to kill one thousand enemies and lose eight hundred of his own.

Lin Nan exchanged more than ten or twenty TNT explosives and distributed them to the controlled fireflies one by one.

"Be good, don't fight, one for each insect, and give these things to your elders later!"

After they all took them, several people took advantage of the gap when the fireflies did not come out and quickly left the place.

Chu Mengyao controlled them to walk towards their nest.

Seeing these more than twenty fireflies coming back, the surrounding fireflies quickly surrounded them and looked at the strange black things on them curiously.

Some even went up to take a bite, but it didn't matter. The TNT exploded instantly, and the rest exploded with it.

"Bang!"

A deafening sound rang out.

More than twenty TNT bombs exploded at the same time, and the scene was spectacular.

But because the cave was particularly large, even these TNTs did not blow it down.

However, the number of dead fireflies was innumerable.

However, there was no kill point for killing creatures in the secret realm, so Lin Nan's move was purely to reduce their number.

The reason why he killed 1,000 enemies and lost 800 of his own was that with the explosion, all the mutant fireflies remaining in the cave came out.

Perhaps to avoid the explosion, they were omnipresent.

There were countless caves here, but nearly a hundred still escaped to Lin Nan's side.

From this point, we can see the large number of fireflies in the cave.

"Brother Nan, what should we do?" Chu Mengyao was a little anxious when she saw so many fireflies.

Lin Nan shouted loudly,

"At this time, we can only run, don't stop, keep running!"

As they spoke, the fireflies had already killed them.

The dense burning flames shot at them from all directions like light.

Once hit, Lin Nan would be fine and might not die, but the two girls would definitely be chilled to death.

At this critical moment, a huge iron block suddenly appeared and took all the damage.

"You finally decided to use it, metal element controller!"

Lin Nan looked at Xiaoze, and when he saw the iron block, the first thing he thought of was the harmless Miss Xiaoze.

She had always concealed the fact that she was a metal element controller. Although he didn't know why she concealed it and didn't intend to use it from the beginning, Lin Nan still knew her ability.

Because he had a system.

Because of this, Lin Nan had always been wary of her, fearing that she would get an iron spear from somewhere and launch a sneak attack.

But she was also well-behaved. Lin Nan didn't sense the sense of crisis coming from her, which also meant that she didn't mean to hurt Lin Nan.

Now she finally used her ability, which was the first step to be honest.

However, at this moment, Lin Nan noticed that she had been holding her stomach while performing the skill.

Lin Nan suddenly realized that she might not use her ability because she was injured!
